Embodiments of the value inheritance widget system 100 allow a user or administrator know the scope of a change to a widget before interacting with the widget. Some embodiments of the value inheritance widget system 100 allow a user to efficiently edit configuration settings and controls without the frustration of pop-up boxes. Some embodiments of the value inheritance widget system 100 allow a single view of multiple values in a graphical user interface, while distinguishing the origin of the values and indicating the scope of impact of a change to a value before user interaction.

FIG. 2 depicts a schematic diagram of one embodiment of a computer server system 200 that relies upon levels of inheritance to which the value inheritance widget system 100 of FIG. 1 may be applied. In the depicted computer server system 200, application 1 202 resides on application server 1 210. Application 2 204 resides on application server 2 212. Application 3 206 resides on application server 3 214. Application 4 208 resides on application server 4 216.

The behavior and operation of applications servers 210-216 may be defined in files consisting of attribute-value pairs. The attribute-value pairs may specify the names of properties and their values and may be managed through a graphical user interface. Settings and values may be inherited from one configuration file to another. In the depicted computer server system 200, application server 1 210 uses the configuration settings of configuration file or configuration data 1 218. Application server 2 212 uses the configuration settings of configuration file or configuration data 2 220. Application server 3 214 uses the configuration settings of configuration file or configuration data 3 222. Application server 4 216 uses the configuration settings of configuration file or configuration data 4 224.

An administrator of the computer server system 200 may define common settings shared by multiple servers. Defining common settings in such a manner allows the administrator to effect a change in a single place and inherit the change in all settings within an inheritance chain. The values or settings in configuration file or configuration data 5 226 are included in both application server 1 210 and application server 2 212. The administrator may change a setting in either application server 1 210, or application server 2 212, or both. A change to a value or setting in configuration file 1 218 will not affect configuration file 2 220. Likewise, a change to a value or setting in configuration file 2 220 will not affect configuration file 1 218. A change to a value or setting in configuration file 5 226 will affect both configuration file 1 218 and configuration file 2 220.

Similarly, the values or settings in configuration file or configuration data 6 228 are included in both application server 3 214 and application server 4 216. An administrator may change a setting in either application server 3 214, or application server 4 216, or both. A change to a value or setting in configuration file 3 222 will not affect configuration file 4 224. A change to a value or setting in configuration file 4 224 will not affect configuration file 3 222. A change to a value or setting in configuration file 6 228 will affect both configuration file 3 222 and configuration file 4 224.

The values or settings in configuration file or configuration data 7 230 are included in all four application servers 1-4 210-216. A change to a value or setting in configuration file 7 230 will affect both configuration file 5 226 and configuration file 6 228. An administrator may make changes at the application level or a higher environment level. For example, the settings in configuration files 1 218 and 2 220 may define settings for server behavior in a test environment and configuration files 3 222 and 4 224 may define settings for a production environment. The settings of configuration file 7 230 are global and are inherited by both the test environment and the production environment.

The inheritance scheme of computer server system 200, as depicted in FIG. 2, may be applied to more complex schemes and to any number of levels. While the depiction outlined in FIG. 2 refers to server configuration settings, the value inheritance widget system 100 may be applied to any system or application that relies upon levels of inheritance.
